Complete!
[root@localhost blctrl]#

2、启动刚才在命令行中刚才安装的软件：

[root@localhost blctrl]# gnome-tweaks

3、在启动的设置窗口中，选择windows项，并且设置Maximize和Minimize为ON：

?

4、在打开一个终端，窗口上最大化和最小化按钮出现了：

?

设置启动时默认进入图形用户界面：

在root用户权限下：

查看当前启动模式

systemctl get-default

[blctrl@localhost ~]$ systemctl get-default
graphical.target

更改模式命令：

由命令行模式更改为图形界面模式：systemctl set-default graphical.target

由图形界面模式更改为命令行模式：systemctl set-default multi-user.target

跟以前使用的linux版本一样，编辑 vi /etc/inittab 文件，修改系统初始化方式

[blctrl@localhost ~]$ cat /etc/inittab
# inittab is no longer used.
#
# ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# Ctrl-Alt-Delete is handled by /usr/lib/systemd/system/ctrl-alt-del.target
#
# systemd uses 'targets' instead of runlevels. By default, there are two main targets:
#
# multi-user.target: analogous to runlevel 3
# graphical.target: analogous to runlevel 5
#
# To view current default target, run:
# systemctl get-default
#
# To set a default target, run:
# systemctl set-default TARGET.target

查看以及修改主机名

[root@localhost blctrl]# cat /etc/hostname        # 查看主机名
localhost.localdomain
[root@localhost blctrl]# hostnamectl set-hostname areadetector   # 修改主机名
[root@localhost blctrl]# hostnamectl                             # 查看修改之后的主机名
